Group 2 (AS)

• As you go down the group 2 hydroxides, solubility increases. As this increases, so does the pH of the solutions formed.
• The more of the hydroxide that dissolves, the greater the concentration of hydroxide ions in the solution formed.
• Down group 2, atomic radius increases due to more shells of electrons.
• 1st ionisagion energy decreases down group 2 because of a bigger atomic radius and more shielding.
• Melting points decrease down group 2 as the atoms get bigger so charge density decreases.
